BUTTON.

SPECIFICATION forming part of Letters Patent No. 666,005, dated January15, 1901.

Application filedJuly 30, 1900. Serial No. 25,218. (No model.)

This invention relates to buttons; and it has for its object to provideasimple and improved button capable of ready and convenient attachmentand detachment without sewing and which will when in operative positionhave a positive and firm hold upon the fabric to which it is secured.

The invention consists in thenovel construction and arrangement of partshereinafter specified.

In the drawings which form part of this specification, Figure l is atransverse sectional view of a button constructed according to myinvention, showing the same in operative position. Fig. 2 is afront viewof the button in detached and partly-assembled position. Fig. 3 is afront view of the button in detached and fully assembled position. FigAcis a perspective View of the button-back.

. prongs 7, arranged adjacent the periphery manufacture the member Aminus the locking-tongue 8 may be struck up from a single blank, and thelocking-tongue may be riveted or soldered in place.

The member B or button-front comprises two fiange or rim portions 9 andl0, respectively, the front one of which, 10, is preferably oval inpheripheral contour. These rim portions are connected centrally by a hubor shank l1, also of oval form, whereby an oval groove or annular recessis formed between the iianges and surrounding the hub or shank ll. Themember B is provided with a transverse bore 12, which passes axiallythrough the hub or shank l1 and is elongated transversely, as shown, sothat it is adapted to pei-mit the passage of the corresponding flatspear-head 8. The bore l2 is provided in the outer face of the flange l0with side recesses 13.

In assembling the members Aand-B the spear-shaped head 8a of thelocking-tongue 8 is initially passed through the bore l2, which isaccurately formed to receive the same, and the member B is then axiallyturned with relation to the tongue 8 until the spear-head SiL is seatedin the recesses 13, when detachment of the members A and B is prevented.

In securing the button to a piece of fabric (shown at 14) or to agarment the prongs 7 of the member A are forced thereinto at one sidethereof, being formed, preferably, of such length as to be entirelyreceived and confined by the fabric, the lockingtongue 8 being forcedthrough and caused to project a predetermined distance beyond thefabric. The member B is then impaled upon the lockingtongue and pressedfirmly against the fabric until 'the head 8 projects forwardly thereof,when the member B is rotated upon the locking-tongue until the head 8arides into the recesses 13. If the length of the locking-tongue be dulyproportioned to the thickness of the fabric 14, a certain pressure ofthe member B will be required to seat the head 8a in the recesses 13,and as soon as this-pressure is relaXed the spring quality of the metalplate 6, due to its annular portion b'a of decreased thickness, willcause a firm retention of the head S1L in the recesses 13, thuspreventing relative movement and accidental detachment of the members Aand B.

The inner face 9a of the flange portion 9 of the member B is preferablysmooth and plane to secure an even bearing upon the fabric, whereas theouter face l0a of the flange portion 10 is concave, whereby the head 8ais prevented from projection beyond the periphery thereof and iseectively protected against IOO vWearing-apparel.

The oval recess or groove between the flange portions 9 and 10 of themember B preferably tapers inwardly, and it is designed to convenientlyconform to and receive the end portion l5 of a suspender, which isusually of oval contour with an oval buttonhole 16. The button member Bis thus particularly adapted for engagement with the ordinary sus penderend or tab, fitting the same snugly and tending in its lconnectiontherewith under stress to assist in the prevention of relative movementof the members A and B.

I do not desire to be understood as limiting myself to the specilicdetails of Construction and arrangement as herein described andindicated, as it is manifest that variations and modifications may bemade in the features of construction and arrangement and in theadaptation of the button to various conditions 0f use without departingfrom the spirit and scope of my invention and improvements. I

`claim and desire to secure by Letters Patent- A button, comprising twoseparable members, one of which consists of a spring-plate l having acentral area of decreased thickness,

a locking tongue carried centrally of the spring-plate, and prongscarried at the periphery of the spring-plate andadapted for engagementwith a supporting fabric, and the other of which members is formed toreceive said locking-tongue, substantially as and fo the purpose setforth.

In testimony whereof I have signed my-
